JHFLYCO 20L Waterproof Sling Pack
The JHFLYCO 20L Waterproof Sling Pack is built for anglers who don't back down from weather, water, or tough terrain. Whether you're hiking through rain or wading deep, this fully submersible pack keeps your gear bone dry and right where you need it.
Crafted from rugged 500D PVC with seam-welded construction and sealed tight with a TIZIP® waterproof zipper, it's built to handle whatever the day throws at you. The padded, adjustable shoulder strap is designed for all-day comfort and can be worn left or right, while a stabilizing waist strap keeps the pack secure during high movement or deep wades.
Inside, the 20L capacity offers generous storage for fly boxes, layers, tools, and more—without adding bulk. An internal mesh pocket keeps tippet, leaders, and small essentials visible and organized, while an integrated Velcro fly patch gives you a dedicated spot to dry and stage your flies between fish. A dedicated landing net sleeve fits the JHFLYCO 37" Landing Net perfectly, and the external D-rings, gear anchors, and water bottle holder ensure everything else has its place. Sturdy, reinforced attachment points stand up to hard use, so you can rig on tools, nets, and accessories with total confidence.
From stormy floats to remote backcountry streams, this waterproof sling pack is the gear-hauler you'll count on when the conditions get real.
